Further, the holder 383 is a rotation shaft 381A, 382A that rotatably supports two rollers, respectively.

Next, the rotation shafts 381A and 382A and the drive shaft M1a of the motor M1 are interlocked by a timing belt mechanism (power transmission mechanism) 39 on the side opposite to the front roller 381 and the rear roller 382 via the holder 883.

That is, the timing belt mechanism 39 is provided with the toothed pulleys 391, 392, and 393 on the rotation shafts 381A and 382A of the front roller 381 and the rear roller 382 and the drive shaft M1a of the motor M1, respectively. The wheels 391, 392, and 393 are wound around the timing belt 394, and the both sides of the bracket 384 are provided with stretch pulleys 395 that are respectively pressed against the outer circumferential surface of the timing belt 394. The stretching pulley 395 is attached to the side surface of the holder 383 through the bracket 396.

The timing belt mechanism (power transmission mechanism) 39 transmits the rotational power of the drive shaft M1a of the motor M1 to the rotation shafts 381A and 382A of the front and rear rollers on the opposite side of the front and rear rollers 381 and 382 via the holder 383.

As described in detail, the timing belt mechanism (power transmission mechanism) 39 is attached to the rotation shafts 381A and 382A of the front and rear rollers and the toothed pulleys 391, 392, and 393 of the drive shaft M1a of the motor M1, respectively. The timing belt 394 is attached to the toothed pulley.

Further, on the belt supply path between the front roller 381 and the rear roller 382, a cutter 301 for cutting the belt body is movably mounted on the upper surface of the movable block 33. The communication wrist 307 that applies the vertical movement to the cutter 301 is disposed on the rear side in the Y-axis direction of the front roller 381 and the rear roller 382. An integrated rod (compression rod) 302 is provided in the cutter 301.

In other words, the belt feeding mechanism unit 38 includes a communication wrist 307 that holds the cutter 301 on one end side and moves up and down together with the cutter 301, and is supported by the communication wrist 307, and moves up and down together with the cutter 301, and The pressing bar 302 of the belt body on the belt supply path is pressed.

Further, a belt seam sensor 303 and a belt sensor 305 are disposed to face the upper side of the belt supply path.

In a state in which the cutter 386 is actuated, as shown in FIG. 15, the press lever 302 presses the belt T from above by the leaf spring in a state where the cutter 301 is actuated. Thereby, the belt T offset is prevented from occurring when the belt feeding device 3 moves forward and backward. When the tape body T is placed on the tape supply device 3, the tape T is removed by hand, and the tape body T before replacement is taken out, and the tape body T to be used is inserted to bring the tape body end against the side of the cutter 301. The rod 302 is placed back and fixed.

That is, the pressing lever 302 is supported by the communication wrist 307, and moves up and down together with the cutter 301 to press the belt T on the belt supply path.

As shown in FIGS. 16 and 17, the belt feeding mechanism unit 38 is provided with a swing holder 383 for switching the front roller 381 and the rear roller 382.

The roller switching mechanism 330 is constituted by a connecting rod 332, a cylinder unit (wheel switching cylinder) 335, and the like.

A fastening pin 398 is fastened to the downwardly extending portion 397 formed by the bracket 396 attached to the rear side of the side surface of the holder 383. The fastening pin 398 is inserted into the long hole 333 formed at the front end of the coupling rod 332. The connecting rod 332 is rotatably supported by the second support shaft 331 which is fixed to the side surface of the movable block 33.

Further, a cylinder unit 335 having a piston rod 336 facing upward is disposed at a rear end of the coupling rod 332. The cylinder unit 335 is fixed to the side of the movable block 33. The rear side of the connecting rod 332 is coupled to the upper end portion of the piston rod 336 via the connecting small wheel 334.

That is, the roller switching mechanism 330 swings the holder 383 with the two rollers as a fulcrum, and only one of the two rollers is selectively crimped to the belt.

As described in detail, the roller switching mechanism 330 has a coupling rod 332 that is coupled to the holder 383 at one end side, a second shaft 331 that rotatably supports the coupling rod 332, and a rear end of the coupling rod 332. The cylinder unit 335 is connected to each other.

When the rear roller 382 is retracted to the belt supply path to convey the belt body (FIG. 17), as shown in FIG. 18, when the cylinder unit 335 is operated to lower the piston rod 336, the connecting rod 832 is the second branch of the intermediate portion. The shaft 331 is a fulcrum and swings clockwise. Thereby, the rear side bracket 396 is moved upward by the long hole 333 and the fastening pin 398, and the holder 383 integrated with the bracket 396 swings counterclockwise with the center support shaft 385 as a fulcrum. Thereby, the front roller 382 is lowered by the belt supply path, and the front roller 381 is lowered to the belt supply path to convey the belt body.

The sewing operation of the belt body Tm for the body LI (or RO) by the belt sewing device is started as shown in Figs. 21, 22, and 23.

In the sewing state in which the belt body Tm is supplied to the body LI (or RO), as shown in Fig. 21, when the sewing is started, the needle 22 is passed through at least three times on the body LI (or RO). By plugging in the upper line NT of the needle 22 and by the hook The lower thread to be supplied forms a stitch in the body LI (or RO) to make the upper and lower lines perform nodules.

Thereafter, when the supply of the belt body Tm is started on the large body LI (or RO), as shown in Fig. 22, the front roller 381 is rotated to supply the belt body Tm to the needle 22, and to abut the needle 22 and the large The upper line NT connected to L1 (or RO). Among them, Tm1 is the belt body that was previously sewn.

Thereafter, as shown in FIG. 23, the body LI (or RO) is moved in the belt supply direction by the XY feeding device, and the front roller 381 is rotated to convey the belt body, whereby the needle 22 is inserted twice or more. On the belt body Tm on the body LI (or RO), the belt body Tm is sewn to the body LI (or RO) by the upper and lower lines.

At this time, the XY feed device is operated by transmitting a large body at a small sewing pitch of 1 mm before and after (for example, 0.7 mm to 1.3 mm) which is smaller than the usual sewing pitch (for example, 2 mm to 2.5 mm), and At this time, the belt feed amount is such that the motor M1 is operated such that the feed amount is equal to or smaller than the small-scale sewing pitch. Since the actual belt feed amount varies depending on the characteristics (hardness, stretchability, and smoothness) of the belt body to be used, the setting amount for the motor M1 can be changed by the display device 6.

Thereafter, the large body LI (or RO) is conveyed at a usual sewing pitch and the belt body Tm is sewn.

As described above, at the start of sewing, when the needle 22 is penetrated to a small-scale sewing pitch of 1 mm before and after the usual sewing pitch, two stitches or more are formed on the belt body Tm on the large body LI (or RO). When the stitches are as shown in Fig. 24, the intermediate presser foot 23 is lowered to the extent corresponding to the thickness of the body, and The intermediate presser foot 23 is lowered to press the belt body Tm against the body LI (or RO). Thereby, the belt body Tm is surely held on the body LI (or RO).

Thereafter, when the belt body Tm is sewn at a normal sewing pitch, the height of the intermediate presser foot 23 is restored to a normal height, that is, a height corresponding to the thickness of the body and the thickness of the belt body.

The elongated strip T (for example, a generally wide strip Tm) loaded on the belt frame 4 has a limited length, so that the end is overlapped with the beginning of the other strip T, and is used by subsequent joining. This repeating portion is not suitable for sewing, so it is usually necessary to perform the cutting before sewing. In the present embodiment, the gold reflective tape body is adhered to the tape joint portion (belt joint) TG.

As shown in Fig. 25, the belt seam sensor 303 is disposed on the upper surface of the movable block 33 through the holder 304, and the belt seam TG is detected on the belt housing side by the phototube.

As shown in Fig. 26, the strip sensor 305 is disposed on the upper surface of the movable block 33 via the holder 306, and the strip T is detected at the strip end side by the phototube.

When the belt seam portion TG reaches the belt supply path on the belt supply device 3, as shown in Fig. 25, the belt seam sensor 303 detects the light reflected by the belt joint TG in the gold belt body.

By this detection, the cutter 301 is operated to cut the belt body Tm before the belt seam TG conveyed by the rear roller 382, and again after the belt joint TG conveyed by the rear roller 382 On the side, the cutter 301 is operated to cut the belt body Tm.

That is, the belt seam sensor 303 is opposite to the two rollers 381, 382. It is disposed on the upstream side in the feeding direction of the elongated belt to detect the seam of the belt.

The cut tape joint TG is fed out by the front roller 381, and as shown in Fig. 26, the tape body sensor 305 obtained by the phototube is used to detect the tape feed.

In other words, the belt sensor 305 is disposed on the downstream side of the belt feeding direction with respect to the two rollers 381 and 382 to detect the presence or absence of the belt.

When the belt seam TG is removed, as shown in FIG. 27, the operator removes the cut belt seam TG that has been fed by the finger and removes it.

Here, the front end of the movable block 33 placed on the tape body T is a surface that is reflected by a plating process.

According to the cutting position (size) of the tape joint TG after cutting, three states of Figs. 38(a) to 38(c) occur.

Fig. 38(a) shows the case where the strap seam TG is located just below the belt sensor 305. At this time, if the operator removes the belt seam TG, the detection of the belt sensor 305 is switched to ON (gold). Belt body → OFF (band body) → ON (no belt body = surface of movable block 33).

38(b) When the strap body sensor 305 is located behind the belt seam TG, if the operator removes the belt seam TG, the detection of the belt sensor 305 is switched to OFF (belt) → ON (No belt = surface of movable block 33).

38(c) In the case where the strap body sensor 305 is located before the belt seam TG, if the operator removes the belt seam TG, the detection of the belt sensor 305 is switched to OFF (belt) → ON (Gold belt body) → OFF (band body) → ON (no belt body = surface of movable block 33).

In any case, if the belt joint TG is removed, the belt sensor The 305 system will switch from OFF to ON.

The control circuit in the above-described tape sewing device is realized by the configuration of the block diagram shown in FIG.

In FIG. 39, at least a ROM, a RAM, and a CPU are disposed inside the control box 5, and are connected to the sewing machine 2, the belt supply device 3, the belt rack 4, and the display device through an I/O circuit (not shown). 6. Bar code reader 7.

The ROM is a non-volatile memory means, and has a plurality of sewing modes, and a sewing program for controlling the sewing operation of the sewing machine in a predetermined sewing mode and various devices for controlling the tape sewing device are stored in advance. A control program such as a sewing program with a body sewing action or a preset data.

The RAM is a memorable erasable memory means for memorizing input information from the operation panel of the display device 6 or the bar code reader 7, or a program or material selected to be read by the ROM.

The CPU constitutes a control unit that executes various programs stored in the RAM or the ROM.

Next, the control of the belt sewn device by the above configuration will be described in accordance with the flowchart subsequent to FIG.

Among them, the following control is processed by the aforementioned control unit (CPU).

In the general flowchart (Fig. 28) in which the belt is sewn, first, the power source is turned on (step S1), and the belt supply device 3 is initialized (step S2).

Fig. 30 is a flowchart showing the initialization of the tape supply device 3 (step S2), searching for the origin of the movable belt guide 35 (step S201), and the movable belt guide 35 (belt width + width) The correction value is moved (step S202). Connect The belt supply device 3 is moved to the standby position (step S203), the front roller 381 is lowered, the rear roller 382 is raised (step S204), and the cutter 301 is lowered (step S205), and the processing is terminated.

In the general flowchart of FIG. 28, the tape supply device 3 is initialized (step S2), and waits for pressing of a preparation key (not shown) displayed on the initial screen of the display screen of the display device 6 (step S3). When the preparation key is pressed, the upper presser foot 12 and the lower plate 11 are moved to the workpiece placement position (the initial position shown in Fig. 5) (step S4). Next, the upper presser foot 12 is raised (step S5), and the positioning pin (reference pin 16) is raised (step S6).

Next, it is determined whether or not the bar code read by the bar code reader 7 is read (step S7), and if there is a bar code reading (YES in step S7), the shoe size and the tape width are obtained based on the bar code (step S8). ). Next, it is judged whether or not there is a belt width change (step S9), and if there is a belt width change (YES in step S9), the wide correction value is set to 0 (step S10), and will be as wide as the belt body. The LED lamp 48 of the corresponding PL (indicator) lights up, and the other PLs are turned off (step S11). However, if there is no change in the width of the belt in step S9 (NO in step S9), the process proceeds to step S11.

Next, the movable belt body guide 35 is moved (the belt width + the width correction value) (step S12), and the process returns to the step S7 again.

Further, in step S7, if there is no bar code reading (NO in step S7), it is determined whether or not the wide correction value is input (step S13), and if there is a wide correction value input (YES in step S13), the wide area is updated. The value is corrected (step S13), and the process proceeds to step S12. However, if there is no wide-width correction value input in step S13 (NO in step S13), the process proceeds to step S15 in Fig. 29 .

Here, in step S14, the wide correction value is updated, and the sewing mode is moved, and the sewing mode is additionally enlarged or reduced. That is, in the display screen shown in FIG. 3 of the display device 6 of FIG. 1, corresponding to the wide correction value (-0.5 mm in the illustrated example) obtained by the operator setting the touch panel. , move the sewing mode, and even zoom in or out the sewing mode.

Therefore, the display screen of the display device 6 also serves as a setting means for temporarily increasing or decreasing the width of the tape relative to the set value.

29 is a general flowchart of FIG. 28, in which it is determined in step S15 whether or not the start SW (start switch) 20 is ON, and if the start switch 20 is ON (YES in step S15), the inspection of the belt is performed (step S16). When the start switch 20 is OFF (NO in step S15), the process returns to step S7 again.

The belt inspection subroutine (step S16) is executed as shown in the flowchart of FIG. 31, and it is judged whether or not the belt belt sensor 47 corresponding to the belt width is ON and the other frame is used. The belt sensor 47 is OFF (step S1601), and if the belt belt sensor 47 corresponding to the belt width is ON and the other belt body sensor 47 is OFF ( In step S1601, YES), it is detected whether or not the supply belt is present (step S1602). In other words, the sewing start is performed by the manual work of the operator, and the belt supply path of the belt supply device 3 is placed in a state where the front end portion of the belt Tm is pressed against the cutter 301. In the process of detecting the presence or absence of the supply belt body, it is determined whether or not the belt body Tm is disposed in the upstream portion of the belt supply path by the belt joint sensor 303 provided on the belt supply path.

Next, when it is determined that there is a tape by detecting the presence or absence of the supply tape (YES in step S1602), it is set to OK (step S1603), and the processing is terminated.

In the case where the rack belt sensor 47 corresponding to the strip width is ON and the other rack belt sensor 47 is not OFF in step S1601 (NO in step S1601) It is set to NG (step S1604) and the processing is ended.

In addition, when it is determined that there is no tape by detecting the presence or absence of the supply tape in step S1602 (NO in step S1602), NG is set (step S1604), and the process is terminated.

In Fig. 29, the tape inspection is continued (step S16), it is judged whether or not the tape inspection is OK (step S17), and if the tape inspection is OK (YES in step S17), the AB sensor (large body sensor) is performed. 17) inspection (step S18).

On the other hand, when the tape inspection NG (NO in step S17), the display device 6 displays "no material" and returns to the processing of step S7 again. Here, when the tape joint sensor 303 detects that the material (belt) is placed (step S18), the display of "no material" on the display device 6 disappears.

In the flowchart of the AB sensor inspection (step S18) shown in FIG. 32, it is determined whether only one of the left and right body sensors 17 is ON (step S1801), if the left and right body sensors are When only one of the 17 is ON (YES in step S1801), the state of the left and right body sensors 17 is acquired (step S1802). That is, which of the left and right is ON? .

That is, in step S1802, as shown in FIG. 37, if the left body sensor 17a is ON, the left outer side LO or the right inner side body RI is placed on the auxiliary table 1, and if When the right body sensor 17b is ON, the left side inner body LI or the right outer side body RO is placed on the auxiliary table 1.

Next, after the processing of step S1802, it is set to OK (step S1803) ends the processing.

However, in step S1801, if only one of the left and right large body sensors 17 is not ON (NO in step S1801), NG is set (step S1804), and "waiting to place the workpiece" is displayed on the display device 6. And the end of the process.

Here, if the material (large body) is placed and only one of the left and right large body sensors 17 is set to ON, the display of "waiting for the workpiece" on the display device 6 disappears.

In FIG. 29, the AB sensor check is continued (step S18), it is judged whether the AB sensor check is OK (step S19), and if the AB sensor checks OK (YES of step S19), the IO sensor is performed. The position calculation of the large body sensor 18 (step S20), and if the AB sensor checks NG (NO in step S19), the process returns to the process of step S7 again.

In the flowchart of the IO sensor position calculation (step S20) shown in FIG. 33, the large body sensor 17 (17a, 17b) of the shoe size/left and right is used to sense the body to the left and right. The mode No. or the coordinate of the inspection position of any one of the devices 18 (the position information of any of the left and right body sensors 18 is acquired) (step S2001), and the process ends.

That is, if the left body sensor 17a is ON, the left body sensor 18a is selected as the IO sensor, and the inspection position is obtained, if the right body sensor 17b is ON. The right body sensor 18b is selected as the IO sensor, and the inspection position is obtained. As shown in Fig. 37, in the present embodiment, the left and right large body sensors 17, 18 are symmetrically arranged, and the inspection positions of the left and right body sensors 18 are the distances in the longitudinal direction D.

In FIG. 29, the IO sensor position calculation is continued (step S20), The upper presser foot 12 is lowered (step S21), the reference pin 16 is lowered (step S22), and the lower plate 11 and the upper presser foot 12 are moved together with the large body sandwiched therebetween to the right and left. The inspection position of the device 18 (18a, 18b) (step S23) is performed by the left and right body sensors 18 (step S24).

In the flowchart of the IO sensor inspection (step S24) shown in FIG. 34, it is determined whether or not the left and right body sensors 18 are all ON (step S2401), and if not all of them are ON (NO of step S2401), Any of the left and right body sensors 18 obtained by the AB sensor inspection (inspection of the body sensor 17) performs IO detection (step S2402).

That is, in step S2402, in the step S1802 of the AB sensor inspection (step S18) of Fig. 32, if the left body sensor 17a is ON and the left side outer body is placed on the auxiliary table 1, When the LO or the right inner side is large RI, the left body sensor 18a is OFF, and the auxiliary table 1 is provided with a lower left (large width) left outer body LO under the ankle, and, left, The large body sensor 17a is ON, and the left body sensor 18a is ON, and the auxiliary table 1 is provided with a right inner side large body RI having a high height (wide width) under the ankle.

Further, in step S2402, if the right body sensor 17b is ON in the step S1802 of the AB sensor inspection (step S18) of FIG. 32, the left inner side LI is placed on the auxiliary table 1. Or when the right outer side is large RO, the right side body sensor 18b is OFF, and the auxiliary table 1 is placed with a lower right (width wide) right outer side body RO under the ankle, and, in addition, the right side The large body sensor 17b is ON, the right body sensor 18b is ON, and the auxiliary table 1 is provided with a left inner side LI having a high height (wide width) under the ankle.

Next, after the processing of step S2402, the sense of the big left and right The state of the measuring device 18/shoe size/the state of the left and right body sensors 17 determines the length of the tape body, and selects the optimum sewing mode among the plural sewing modes (step S2403), and sets it to OK (step S2404) and ends. deal with.

In the case where the left and right large body sensors 18 are all turned ON (YES in step S2401), NG is set (step S2405), and the "workpiece placement abnormality" is displayed on the display device 6, and the processing is terminated.

In FIG. 29, the IO sensor check is continued (step S24), it is judged whether the IO sensor check is OK (step S25), and if the IO sensor checks OK (YES of step S25), it is selected according to The sewing mode is performed to perform sewing (step S26).

In the flowchart of the sewing (step S26) shown in FIG. 35, the sewing is normally performed until the next "belt supply command" or "sewing end command" (step S2601), and it is determined whether or not the tape supply command is executed (step S2602), if the tape supply command is issued (YES in step S2602), the tape seam sensor (belt joint sensor) 303 is inspected (step S2603), and it is judged whether or not there is a body joint (belt joint) TG (step S2604).

However, in step S2602, if the supply instruction is not the tape supply (NO in step S2602), the processing is terminated.

In step S2604, if there is no body seam (belt joint) TG (NO in step S2604), it is determined whether or not the seam flag is ON (step S2605), and if it is not the seam flag ON (NO of step S2605) The cutter 301 is raised (step S2606), and the rear roller 382 is lowered (step S2607) to determine the predetermined belt body in step S2403 of the IO sensor inspection (step S24) of FIG. The tape body T is conveyed to the length (step S2608).

Next, the cutter 301 is lowered (step S2609), the tape body T is cut into a predetermined length, and the front roller 381 is lowered (step S2610).

Next, in order to make the body and the line nodule, only after the large number of needles are sewn (for example, three or more stitches) (step S2611), the front roller 381 transports the belt body T, and the belt body T is abutted against the abdomen of the body and the line. Part (step S2612). The belt system to be conveyed is sent to the needle, which is a position that can be sewn with the body. The tape T at this position is set to a predetermined position at which the tape body starts to be sewn.

As described above, in the initial state of sewing, the cutter 301 is lowered, and the front roller 381 is lowered, and the operator is supplied with the tape T of a predetermined length.

Then, in order to make the belt body and the large body nodule, the belt body T is continuously fed in a predetermined sewing pitch feeding direction, and the number of stitches is sewn at a small sewing pitch (1 mm front and rear, for example, 0.7 mm to 1.3 mm) (step S2613) ). In the case where the sewing pitch feeding direction is such that a stitch is formed along the longitudinal direction (X-axis direction) when the straight body of the shoe is sewn, the belt body formed in the belt supply device 3 is inserted. The direction (the belt supply path) is the X-axis direction.

Thereafter, the rear roller 382 is lowered (step S2615) and sewing is continued. The belt body T is combined by the large body and the wire, and the large body is moved by the feeding (the upper pressing foot 12 and the lower plate 11), whereby the amount required for the stitch pitch is pulled out. Then, it returns to the process of step S2601 again.

Further, if there is a body seam TG in step S2604 (YES in step S2604), the seam flag (joint flag) is turned ON (step S2616), and the length until the seam is set to C. (by the belt seam sensor 303 The length to the cutter 301 is fixed) (step S2617).

Next, it is determined whether the length C to the tape seam TG is > the tape length (step S2618), and if not the length C to the tape body joint TG > the tape length (NO in step S2618), on the display device 6 The display screen displays a seam error (joint error) (step S2619), and as shown in Fig. 26, the belt body including the belt seam TG is discharged (step S2620).

Next, as shown in FIG. 27, it is detected in the state of the tape sensor 305 whether or not the discharged tape has been removed (step S2621), and if the tape has been removed (YES in step S2621), the display device will be displayed. The seam error (not shown) displayed on the display screen of 6 is released (step S2622), and the pressing of the start SW (start switch) 20 is waited for (step S2623). Thereafter, the seam flag is set to OFF (step S2624), and the process returns to step S2606 again.

Here, whether or not the tape body discharged in step S2621 has been removed is determined in the detection switching state of the tape sensor 305. As shown in FIGS. 38(a) to (c), when the tape body is removed in any case, the detection system of the tape sensor 305 is in an "OFF→ON" state, and by detecting the switching state, it can be judged. The discharged tape has been removed.

Further, in step S2605, if the seam flag is ON (YES in step S2605), the process proceeds to step S2618.

In addition, in step S2618, if the length C to the tape seam TG is the tape length (the required tape length) (YES in step S2618), the length until the tape seam TG is set to the tape length. The length of the body seam TG - the length of the belt body (step S2625), returns to the process of step S2606 again.

As shown above, the detection of the belt seam TG is in the belt supply path. The upstream side of the diameter is carried out by the belt seam sensor 303, and the belt body is not wasted compared to the required belt length.

In Fig. 29, the sewing is continued (step S26), the upper presser foot 12 is raised (step S27), and thereafter, the tape supply device 3 is moved to the workpiece setting position (step S28), and the sewing material recovery waiting process is performed (step S29). ).

In the flowchart of the sewing material recovery waiting (step S28) shown in Fig. 36, the state of the AB sensor, that is, the state of the left and right body sensors 17, is obtained. 17 (step S2801), the large body sensor 17 that has been turned ON is turned OFF (step S2802), and the processing ends.

After that, the process returns to the process of step S6 again.

Further, in Fig. 29, if the IO sensor check is not OK in step S25 (NO in step S25), the process proceeds to step S29.

As described above, the control box 5 as a control means rotationally drives the two rollers 381 and 382 to move the cutter 301 up and down.

As described above, the belt feeding device (belt feeding mechanism portion) 38 and the belt sewing device of the embodiment drive the two rollers 381 and 382 by one motor M1, and only the two rollers 381 and 382 are used. One roller is selectively crimped to the belt body to feed the belt body T, so that the belt body T can be stretched less. Further, since the two rollers 381 and 382 are not directly coupled to each other by the belt, the cutter 301 can be disposed between the two rollers 381 and 382, and the discharge of the belt T can be easily performed. Further, it is only necessary to load one motor M1, and the belt feeding device 38 can be miniaturized.

Further, the pressing rod 302 moves up and down together with the cutter 301, and the pressing rod 302 presses the belt body T, thereby preventing the belt body T from being displaced when the belt supply device 3 performs the forward and backward movement.

Further, according to the belt feeding device 38 and the belt sewing device of the embodiment, since the special means for discharging the seam portion of the belt body is not required, it is easy to grasp the belt with the finger when the seam portion of the belt body is discharged. The body seam portion is discharged.

Further, by providing the belt seam sensor 303 and the belt body sensor 305, the cut seam portion of the belt is fed to the belt feeding device 38 by the two rollers 381, 382. After the front end side, it is possible to surely determine whether or not the operator has removed the cut seam portion of the belt with the finger.
